Well, if `ListWrapper` is Enumerable + `Array.prototype` extensions,

True.
We could reduce ambiguity by having some kind of a generic rule - e.g.
"all accessor methods always act on the first item". This should be

Cool.
I forked prototype, and started working on NodeWrapper/NodeListWrapper
- http://github.com/kangax/prototype/tree/master/src/element.js
Accompanying tests are there as well (although the test suite is far
from being complete).
